Bimetallic thermometer is mainly used in industrial equipment, HVAC equipment, power plant, marine, etc.As long as the temperature sensing tube of bimetal thermometer is inserted into the measured medium, how to choose the stem length of industrial bimetal thermometer?
The above figure shows back connection bimetal thermometer as an example,Two factors need to be considered in calculating its stem length.One is the installation method and the total installation height;The other is the insertion depth of the environment and whether the insertion depth is connected to the thread?The details are as follows:
If the installation method is screw thread or flange connection,stem length = total mounting height - gauge height - thread or flange height - mounting base height (if there be);This calculation method is only suitable for back connection bimetallic thermometers.If radial or bottom connection bimetallic thermometer is not applicable;
If the insertion depth is connected to the thread,Stem length = insertion depth -thread height;If the insertion depth is not connected with thread, stem length = insertion depth.
